to give you something of a measure of the value of the thing ... i paid $9k for this old 1998 L3010 4wd hst last year. the guy could've gotten $15k easily except that he thought the 4wd was going out in it (that was just replacing a splined drive shaft). this one had 2100 hrs when i bought it. the lift cylinders on the fel were leaking, but the seal kits were not expensive and there are some great instructional videos on youtube for that, so that fixed up my drips in the hydraulic system in an afternoon.
have a look at the supply hoses to the front end loader would be my only advice, especially if it's been sitting. check for dry rot/cracks before you fire it up. it takes no time at all to dump 8 gallons of hydraulic fluid on the ground at 8-10 gpm flow rates. since the tranny uses the same fluid reservoir, there it sits until you go and get fluid and hoses.
